ELECTRICLIGHT Application filed January r15, 1921; Serial No.,437,411.

To all lwhom 'may concern.'

' Be it known that we, PnRoY useful Improvementsv in Electric-Light Fixtures, of which the following is a: specifica-` tion. y

Our invention relates to electric lighting fixtures of the indirect or semi-indirect type This typerof fixture usually includes a ceiling reflector ordinarily made of some suitable plastic composition, and one of the objects of our invention is to provide a construction of lighting fixture in which the reflector is reenforced and supported or suspended from the usual union or nipple which has a firm anchorage in the ceiling.

Another object of the invention is to improve the means by which the shade, forming a part of the iixture, is supported in position beneath the lamp; the shade being readily attachable and removable and not dependent for its support on the lamp socket.

A still further object of the invention is to generally simplify and improve the construction o such lighting fixturesl by reducing the number of their parts to the minimum and so coordinating the parts that a. maximum of strength with a minimum of weight is obtained.

The form of invention at present preferred by us is illustratively exemplified in the accompanying drawing, in which Fig. 1 is a substantially central vertical sectional view of the improved fixture installed in a ceiling; Fig. 2 is an elevational view of a stirrup forming a part of theconstruction, and Fig. 3 is a plan view of the shade supporting plate.

Referring by characters of reference to the drawing, A denotes the general plane of the ceiling in which is rigidly held the internally threaded union 10 through which the leading in wires (not shown) pass, as is customary in devices of this general type. Engaging the union 10 and depending therefrom is an externally threaded pipe 11 from which the reflector 12 is supported.

The reiiector consists of a suitably shaped plaque, preferably conical with a central opening 13, and may be made of a plastic composition, of iibre or of any other matecording yto. ,our invention, we partially em bed-in the plaque, in the course-of manufacturing the latter, a-k rigid preferably mej-`A tallic sheetory bar 14C' serving as a reen-forcing member for-the plaque, lsaid bar having an openingthrough which thelowerendotv the pipe 11k may pass and the barf :being held onthe pipefll byl a lock'nut 15 or equivalent securing means. Fromkthe foregoing descriptionit willfbenoted thatgthe reflector.v is suspended directly'` from' ythe unionlOif Suspended Jfrom the pipe-11 is a stirrup which comprises the cross head or bar 16 engaging the pipe 11, and the lateral depending arms 17. These arms may be l -rial combining lightnes'sandv rigidity. Aciy l. ELIAS and` MICHAEL ANGELOV ELIAS, 2d, citizens of the.; AUnited States, residing at New York city,

in the county of New York and State of New York, have invented certain new andV threaded at one end, as at 17a, to screw intok the head 16 and their other ends may be provided with heads 18.

The arms 17 support an annular plate 19 from which the shade 20 is suspended. The

plate 19 has diametrically opposite key slots.

21 therein, whereby the plate may be placed in position by passing the heads 18 of the arms 17 through the larger parts of the slots 21 and then partially rotating the plate until the heads are under the narrower parts of the slots, the interlocking action being somewhat analogous to that of a bayonet joint. Secured to or near the periphery of the plate 19 is a plurality, preferably three, rods 23 the opposite ends of which are hooked at 24 to releasably engage with coactinghooks 25 formed on the inner ends of studs 26 which pass through the wallet the shade 20. It will be obvious that the hooks 24 and 25 may be easily engaged and disengaged to permit-of installation and removal of the shade 2O ina very simple manner.

' Plate 19 19 is provided with the central opening 27 with which the open end of socket 22'registers. The socket is Ysecured to the plate by lscrews28 or theirequivalents, and the'usual filament lamp 29 is insertible in and removablev from Vthe socket in the ordinary manner. 'Ehe socket 22 is connected with the leading inlwires, but as these electrical connections are well known in this art` it also serves as a support for the .usual'socket 22, 'and to that end the plate Vthe usual ornamental appearanceV of the device asa whole isV in no way marred. The device may be installed even by persons unskilled in this kind of work, itbeing merely necessary VtoV pass the pipe 11 through the bar head l and Vscrew down the lock nut l5 whereby the reflector and its appurtenant parts are secured in position( Thereafter the lamp 2 9 is inserted in the socket 22 and the shade properly positionedv byinterengagement of the hooks 24 and 25. y

The fixture may jbe provided with the wire conduit 30 terminating externally of plaque 12 in the switch casing 3l having the VVpull chain 32 by'rme'ans of which the switch (not shown) maybe operated.

We claim Y In a lighting fixture, a reflector having a central opening therein, a metal bar einbedded in said reflector, and having a portion` thereof protruding from the reflector,

Y said portion being spaced substantially from and disposed over the opening` inthe reector and having an opening therein axially alined with the opening in the reflector,

and supporting means engaging the said protruding portion through 'said nopening .therein Vto hold thereflector in suspended under surface of the protruding portionof' the bar` and over a depending'wall pipe, and Y A a plate for the opening in the reflector provided with upstanding screws kadapted tol engage the openings in the flange of the nut to support the reflector, said plate being further providedwith an opening to receive the threaded end of a lamp.

In testimony whereof we have aixed our signatures.
